An adult female recently sent to the Zoological Gardens in Calcutta by 

 Dr. Bidie of Madras has her face and ears more suffused with bright scarlet than 

 any M. rhesus I have seen. She has not been sufficiently long under observation to 

 permit of it being ascertained for what length of time this flushing will last. Her 

 nipples are very large and pendent. 



Inhabits the southern parts of India. 



The variety alluded to by Jerdon as existing on the Eastern Ghats seems to 

 me to be only the adult of this species. 



The undermentioned species,^ which is extremely doubtful, has been included 

 by Blyth in his Catalogue of Mammals, but there is no evidence that such a 

 form exists in Formosa beyond what is here stated.

The only information regarding this monkey is contained in a letter from Mr. Swinhoe to Mr. Blyth, published 

 fifteen years ago, and a note by the latter naturalist on a living specimen said to have been procured from the Island 

 of Formosa. 



Mr. Swinhoe, in forwarding to the Calcutta Museum the skull of a Macaque which he had received from Formosa 

 and had kept alive for several months, designated the animal the small Formosan monkey and described it as a native
